Our company has overcome multiple technical challenges in the production process and successfully developed and manufactured a batch of high-quality hydrostatic bearing copper plates that meet the required specifications. These copper plates have a weight of up to 6000 kilograms, with dimensions of φ3300/2200×150mm, made from ZCuPb15Sn7 material, and are used in the Simmerring large forging machine.
The most significant challenges during the manufacturing process stemmed from two major technical difficulties: high lead content and wall thickness issues. The material has a high lead content, and high-lead alloys are prone to centrifugal segregation during the casting process, resulting in uneven alloy composition, which affects the mechanical properties and stability of the copper plate. Additionally, casting large diameters with a significant difference between outer and inner diameters, especially with wall thicknesses exceeding 500mm, brings about unavoidable technical difficulties such as rapid cooling and shrinkage compensation. Severe shrinkage and segregation presented enormous challenges for controlling the casting quality.
Faced with these challenges, our R&D team conducted an in-depth analysis of the casting process and carried out multiple rounds of technical breakthroughs. Through optimizing mold design, improving alloy composition, adjusting cooling rates, and enhancing shrinkage compensation measures, we successfully addressed issues such as uneven wall thickness and lead segregation, ensuring the high quality and stability of the castings.
After rigorous quality inspections and testing, the hydrostatic bearing copper plate met all performance requirements for the Simmerring forging machine, exhibiting excellent mechanical properties and good wear resistance, capable of withstanding high-load operations and providing robust support for the stable operation of large forging machines.
This successful production not only demonstrates our company’s technical strength in the field of high-precision casting but also marks a significant breakthrough in solving complex casting process challenges. This achievement will further drive our company’s technological innovation and market expansion in the high-end equipment manufacturing sector.
We believe that with this technological breakthrough, our company will continue to provide high-quality, stable, and reliable castings for the high-end equipment manufacturing industry both domestically and internationally, creating greater value for our customers.
